INPUTS - The PL series allows you to use three types of input connectors per channel. A XLR female jack for balanced connections, a 1/4
TRS female jack that will accept balanced and unbalanced connectors and a RCA female jack for unbalanced connection. Use these
connections to connect the output signal from a mixer, cross-over or EQ to your PL series amplifiers. A balanced connection is recommended
for cable runs longer than 20ft. When constructing your own XLR cables follow the pin configuration described below for proper connections.
For cable runs shorter than 20ft., you may choose the RCA or 1/4” TS unbalanced input option. These unbalanced input options may be more
convenient for most users due to the abundant supply of prefabricated cables available at your local audio dealer.
OUTPUTS -
BINDING POST/BANANA PLUG: Connect your speakers to the binding post outputs on the
rear of the amplifier. The speaker wire may be connected by bare wire (directly connected,
usually for permanent connections), banana plug, or spade connector. Connections are made
to channel one and channel two outputs for Stereo Mode.
IMPORTANT NOTICE: Although a speaker will operate with the positive and negative leads
plugged into either terminal on the amplifier binding post, be sure to plug the negative lead
into the black terminal and positive lead into the red terminal. Ensuring proper polarity will
avoid speakers being out of phase that can cause a loss of bass response.

BANANA PLUGS: (Figure 7)
When connecting your speakers to the amplifier using banana plug, be sure that the red and black caps on
the binding post are completely screwed in. Insert the banana plug into the caps of the binding post, be sure
that the banana plug is inserted securely to avoid the risk of popping out.
BARE WIRE CONNECTIONS: (Figure 8)
When connecting your speakers to the amplifier using bare wire, unscrew the red and black caps on the
binding post, be sure not to completely remove or unscrew the red and black caps. Strip back the wire
insulation ½” (13mm). Insert the bare wire into the hole that was revealed by unscrewing the binding post
cap. After inserting the wire into the binding post hole, screw the binding post cap down on the wire. To
reduce the risk of shock or damage to your amplifier, be sure that the wire connected to one binding post
does not come in contact with that of another.
SPADE CONNECTOR: (Figure 9)
When connecting your speakers to the amplifier using spade connector, unscrew the red and black caps on
the binding post, be sure not to completely remove or unscrew the red and black caps. Insert the spade
connector into the binding post and tighten the caps down on the spade connector. To reduce the risk of
shock or damage to your amplifier, be sure that the wire connected to one binding post does not come in
contact with that of another.

STEREO CONNECTIONS USING THE NEUTRIK SPEAKON OUTPUT CONNECTORS:
Recent regulatory requirements in Europe have outlawed the use of the dual banana plug and force amplifier users to terminate their speaker
cables with spade lugs or bare wire ends. This is not advantageous to most users that want to reconfigure their systems or quickly change out an
amplifier. The Neutrik Speakon connector provides the most convenient solution to this problem, eliminating the need for spade lugs or bare wire
end cables. Major speaker manufacturers have been using Speakon connectors on their products for years, so chances you are ready to use the
Speakon connection. With Speakon connectors, you can connect straight from the amplifier to the speaker. The Speakon connector used on this
amplifier meets all known safety regulations. Once wired correctly, the connector cannot be plugged in backwards, causing the type of inverted
polarity situations that have become common with banana hookups. This connection will provide a safe, secure and reliable method of connecting
your speakers to your new amplifier. You can purchase the Speakon NL4FC connectors from your local audio dealer.

You will need a pair of Neutrik Speakon NL4FC connectors. You will also need
high-quality two or four conductor Speakon cable, a pair of needle-nosed pliers
and a 1.5-mm Allen key to assemble the Speakon connectors to your speaker
wire. To assemble the Neutrik Speakon NL4FC connector, complete the following
steps:
1. Strip back 3/4-inch of the cable casing. Strip off 1/4-inch from the end of each of
the conductors down to bare wire, and insert the brass fittings ( Figure 10 ).
2. Slide the wire tensioner (D) and the Speakon coupler (E) through the cable end.
See Figure 11.
3. Insert each wire with the brass fittings into the top of appropriate slot of the
connector insert (B) as shown in Figure 12. Use a 1.5-mm Allen key to tighten
the connection ( Figure 13 ).
4. Be sure to properly match the positive (+) and negative (-) leads of each wire (
Figure 14 ).
5. Slide the connector insert (B) into the connector housing (A), making sure that
the large notch on the outer edge of the insert lines up with the large groove on
the inside of the connector housing. The insert should slide easily through the
housing.

PROTECTION
1. SHORT CIRCUIT PROTECTION
The PL series comes with built-in Output Short Circuit Protects. The Output Short Circuit Protection protects the
output devices of the amplifier from short circuits and stressful loads. If your speaker lines shorted, the amplifier
automatically detects this problem and discontinued operation for that channel. If one side of your amplifier becomes
shorted and goes into protect mode, the other side will continue to operate normally. Channel output during the “Short
Circuit Protection" will be interrupted (i.e. no sound output). Short Circuit Protection can usually be traced back to the
signal output line (i.e. speaker line). Check the line from the output terminal of the amplifier to the speaker. If this line
is good, check the internal speaker connections and components. A short circuit will usually be traced to a bad cable
or a bad speaker component and is rarely traced to the amplifier itself.

UNiKA PL-300/PL-500
2. OVERHEATING PROTECTION
The PL series amplifiers are cooled by Single 2-speed fan, and always are kept at moderate temperature. During low level output the fans run at
normal speeds. During high output and as heat raises, (exceeding 50°C.), the fans will run at higher speeds to aid the cooling process. If the
heatsink temperature exceeds 91°C., the amplifier will mute until the amplifier cools down. When the amplifier cools below 90°C., the amplifier will
return to normal operations. Be sure not to operate your amplifier below the minimum load ratings to reduce the risk of overheating problems.
3. DC CIRCUIT PROTECTION
If dangerous subsonic frequencies or direct current (DC) is detected in the amplifier's output, the unit will activate its DC/low-frequency protection
circuitry and the amplifier will be muted.This protects the loads and prevents oscillations. The unit will resume normal operation while the amplifier
no longer detects dangerous low-frequency or DC output.
